SASII HOLDER OR LATCH.

Application filed January 9, 1923.

This invention relates to window sash holders or latches such as are used to hold railway car windows in raised position, and has for its object, a sash holder which is particularly simple in construction, economical in manufacture and highly efficient and durable in use and particularly a construction by which the locking lever is rigidly supported and easily assembled in the casing.

The invention consists in the novel features, and in the combinations and eonstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a front elevation of one form of sash holder embodying my invention.

Figure 2 is a rear elevation thereof.

Figure 3 is a rear elevation of the casing, the lever and spring being removed.

Figure 4 is an edge view looking to the right, Fig. 1.

Figure 5 is a sectional view on line 5-5, Fig. 2.

Figure 6 is a front elevation of another form of such lock embodying a feature of my invention.

Figure 7 is a sectional view on line 7-7,

Fig. 6.

This sash holder comprises generally a casing having a recess opening through its rear face and with a segmental bearing socket in the recess, and an operating angle lever having a hub at its angle mounted to rock in the socket, one arm of the lever extending outside of the casing and serving as a handle, and the other arm being movable from within the recess to the outside thereof and vice versa and serving as a latch.

The lever is so mounted in the recess and the socket as to be removable and replace-' Serial No. 611,684.

3 for lying on the face of the sash and for securemfent thereto by suitable means as screws extending through openings 4 in said flanges. The casing is here shown as provided with a laterally extending rigid pinch handle 5. This handle 5 is provided with a prong 6 on its inner edge which enters the window sash, and aids in securing the casing to the sash. a,

7 is the segmental bearing socket which is located in the lower outer corner of the recess 2, this socket being cylindrioally curved.

8 is the angle lever having a hub 9 at its angle in said socket, and also having one arm 10 thereof extending to the outside of the casing through an opening 11 in the lateral side remote from the socket 7, and overlying the pinch handle 5, and serving as the handle of the lever; and having its other arm 12 movable through an opening 13 in the outerlateral side or edge of the casing from within the recess to the outside of the casing and serving as a latch to engage catches or a rack on the window guide or frame as will be understood by those skilled in the art.

One of these openings 11, 13 and usually both of them open through the rear face of the casing although it is not necessary, except to make the casing as shallow as possible, that only the opening through which the handle arm 10 extends, open through the rear face in order to permit detachment of the lever 8, by an outward axial movement of the lever out of the socket 8 through the open rear side of the casing 1.

Preferably, the" lever is placeable in and removable from the recess 2 and bearing 7 by an axial movement when the lever 8 is in an abnormal position in which the latch arm 12 is located entirely within the recess 2, and the lever and easing are provided with means which normally interlock and prevent axial displacement of the lever.

As here illustrated, the casing is provided with a barrier or shoulder at the rear side of one of the openings 11, 13 which normally overlies the contiguous lever arm 10 or 12, and as seen in Figures 2, 3, the casing is formed with a barrier or shoulder 14: at the lower end of the opening 13 for the arm 12,

and the arm 12 is provided with a portion,

as a tooth 15 normally located'behind said barrier.

A spring usually interposed between the arm 12 and the opposite wall of the eas ing, acts on the lever to thrust the arm 12 outwardly. When this spring is removed,

the lever arm can be depressed far soeket l', this-stud projecting beyond the plane of the rear face of the-casing and in- 2 to a hole in-the window sash. However, the hub 9 of the lever bears on the hearing face of the socket 7.

The spring 16 seats at one end in a socket 18 in one of thelateral sides or edges of the i 2 recess and at its other endsurrounds a stud 19 on-t-hearm 12 of the lever 8.

In Figs. 6 and 7 another form'ot sash latch having a pivoted angle lever-thrusting against a segmental bearing socket, is shown.

" 111 these figures 21 designates the casing which is in the torm of abase orrsupport. "24L isthe bearing socket 25 is the angle lever having its hub' 26 journaled in said socket and arms 27, 28: serving respectively as a handle, and as a latch. 29 is the spring,

it being here shown as a torsion spring lo eated inthe-hub 26 andcoiledabout a stud or rivet 30 extending axially through the hub 26 and having a head 31 overlying the 0' outerface o t=thehub and holdingthe lever from displacement-out of the recess,'bearing and socket.- Thespringhas arms 82, 83 at its ends thrusting against the casing andone arm of the lever, respectively.

5, and 6 and 7, the bearing socket which is of relatively large extent holds the operating lever in alinement as the hub bears on the cylindrical face of the socket throughout the length of the hub. 'Henee, the liability or the lever becoming loose and out of alinement under the severe usage to which these locks are subjected in their normal use, is reduced to a minimum.

lVhat I claim is:

11. A sash holder comprising a casing hav- .ing a recess opening through its rear face, and an angle lever mounted at its angle to rock in the casing and being removable and .i'e1)lac'eable through the open rear side of the casing upon axial movement of the lever, one arm of the lever extending outside of thecasing and serving as ahandle and the Lother being movable into and out of the i casing and serving as a latch, the lever nor- In-each otthe forms showu'in Figs. 1 toinally interlocking with the casing to prevent axial displacement, substantially as and tor the purpose specified.
